The consumer price index (CPI) in 2005 was 83. It was 80.8 in the previous year. This change in CPI is used by the Bureau of Statistics to calculate inflation.

According to the Bureau of Statistics consumer price index, the dollar experienced an average inflation rate of 2.31% per year. Prices in 2018 are 34.6% higher than prices in 2005.

In other words, AU$100 in 2005 is equivalent in purchasing power to AU$134.58 in 2018, a difference of AU$34.58 over 13 years.

The current inflation rate is now 0.45%^{1}. If this number holds, AU$100 today will be equivalent to AU$100.45 next year.

Cumulative price change | 34.58% |

Average inflation rate | 2.31% |

Converted amount (AU$100 base) | AU$134.58 |

Price difference (AU$100 base) | AU$34.58 |

CPI in 2005 | 83 |

CPI in 2018 | 111.7 |

CPI in 2018 / CPI in 2005 * 2005 AUD value = 2018 AUD value

Then plug in historical CPI values. The Australian CPI was 83 in the year 2005 and 111.7 in 2018:

111.7 / 83 * AU$100 =
